Ok, so my newset Betta (Akrin) has been acting weird. During the day, he always sits at the darkest bottom corner of his tank. and he will NEVER go up to the top of surface unless he has to breath, Everytime he goes up there he flipps out. I think it might be his filter Because it poors out the filtered water there. Also at night he freaks out and starts to flare and ram the glass, it might be his reflection but idk, And finaly, When I first got him he had a dead looking fin peice, Im afried it might be fin rot or fin damage.
